comm_slab.c
Purpose:
Execute slab command. Change slab mode or change the position of
front or back slab surface.
Input:
(1) Pointer to MolComplexS structure, with macromol. complexes.
(2) The number of macromolecular complexes.
(3) Pointer to RuntimeS structure, with some runtime data.
(4) Pointer to ConfigS structure, with configuration data.
(5) Pointer to GUIS structure, with GUI data.
(6) Pointer to NearestAtomS structure.
(7) The number of pixels in the main window free area.
(8) Pointer to refreshI.
(9) String which contains slab surface specification and slab
shift.
Output:
(1) Slab surfaces moved.
(2) Return value.
Return value:
(1) Positive (command) code on success.
(2) Negative (error) code on failure.
